HYCODAN (homatropine methylbromide)

Respiratory Approved 1943-03-23

Hycodan helps patients with the symptomatic relief of a cough. This medication is used for adults 18 years of age and older once a healthcare provider has assessed the cause of the cough. It is generally reserved for situations where the benefits of suppressing the cough are expected to outweigh the risks of addiction or misuse associated with its opioid component.

How HYCODAN Works

This medication works by targeting the central nervous system and specific receptors. Hydrocodone acts on the brain's cough center to suppress the coughing reflex, while homatropine acts as an anticholinergic that inhibits the activity of muscarinic acetylcholine receptors.
